It doesn’t work that way. There are no votes in nato. Nato is essentially a treaty. How it works is that a state needs to sign the treaty to join, but then every current signatory needs to ratify the change to the treaty that now includes the new signatory. Unless all members agree on the treaty change, it’s impossible to move forwards, since the treaty itself demands unanimity.

Every state in the treaty needs to be unanimous in letting a new one in and therefore changing the treaty. Kicking someone out would also require unanimity, unless of course they agree to put in some clause that lets them kick them out with like a 2/3 majority for example. But then putting in that clause would also require unanimity.

The only real way to kick someone out fully would be to legally scrap the entire nato treaty, and rebuild it as nato 2. but then you would probably suffer from one or more signatories wanting the fundamental treaty to be slightly different. So that poses it’s own challenges.
